# Load Audio from Asset
> Pick audio from the ComfyTV **project asset library**—reuse Speech/Music Stage output or imports for Video Stage, timelines, or reference audio.
## What this node does
**Load Audio from Asset** lets you browse audio assets for the current project inside the node: categories, search, entry list. A click outputs a `COMFYTV_AUDIO` snapshot—**no ▶ Run**.
Library audio typically comes from **Speech Stage**, **Music Stage**, **Demux**, or sidebar imports. Complements **Load Audio** (`input/` folder).
## When to use it
* Reuse the same voiceover without re-running Speech Stage.
* Wire generated BGM to **Video Stage → audio** (IA2V).
* Feed **Speech Stage → reference\_audio** for cloning/style.
* Optional track on **Director Timeline → audio**.
## How it works (why ComfyTV is designed this way)
* **Instant stage**: Selection → snapshot; no workflow.
* **Snapshots**: Downstream Runs use the selected URL; picking another updates it.
* **Project scope**: Only artifacts under the same **Project** appear.
* **Load vs generate**: This node **loads** existing audio; **Speech/Music Stage** **creates** new audio (key FAQ distinction).
## Types (COMFYTV\_\* vs native ComfyUI)
| ComfyTV type | What it is | vs ComfyUI native |
| --------------- | ------------------ | -------------------------- |
| `COMFYTV_AUDIO` | Audio URL snapshot | Not `AUDIO` tensor |
| `COMFYTV_VIDEO` | Video with audio | Demux to library first |
| Native `AUDIO` | Tensor | **→ ComfyTV Audio** Bridge |

## UI and parameters
### Asset picker
* Thumbnails/waveform (UI-dependent), categories, search.
* Empty library → run **Speech/Music Stage** or import first.
### asset\_url / asset\_id / category (hidden)
* UI-written; category filter persisted.
### project\_id / parent\_output\_id
* Hidden internals.
## Outputs
| Output | Type | Meaning | Typical downstream |
| --------- | --------------- | ----------------------- | ------------------------------------------------------------------------------- |
| **audio** | `COMFYTV_AUDIO` | Selected audio snapshot | Video Stage (audio), Director Timeline (audio), Speech Stage (reference\_audio) |
## Step by step for beginners
1. Add **Project** and name it.
2. Run **Speech Stage** or **Music Stage** (or import via sidebar).
3. **Add Node → Input → Load Audio from Asset**.
4. Click the target audio in the node body.
5. Wire to **Video Stage → audio** or other consumers.
6. **▶ Run** downstream if it's a generator stage.

## FAQ
**Q: vs Load Audio (input/)?**\
A: External files → **Load Audio**. Project generated/imported → **this node**.
**Q: vs Speech Stage?**\
A: Speech **generates**; this **picks** from the library. No TTS here.
**Q: Type mismatch?**\
A: Expect `COMFYTV_AUDIO`; Bridge native `AUDIO` into the library first.
**Q: Empty after category filter?**\
A: Switch to `all`; confirm assets exist in that category.
